Abstract: A wire end of a wire harness is protected. The wire harness includes a wire bundle and a connector connected therewith. The wire bundle includes the wire end, and the wire end includes a bent portion and faces the connector. First, a sheet member is folded perpendicularly to a wire lead-out surface of the connector, thereby forming, concurrently, counter sides facing the wire lead-out surface, side surface covering portions, and a tip end protection portion. Next, the side surface covering portions are folded along a top protection portion formation portion, thereby forming, concurrently, side surface protection portions, a top protection portion and an extending portion. Next, a wire end protection portion is secured, with a pressure-sensitive adhesive tape or the like, to a wire bundle portion while the relative position of the counter sides with respect to the wire lead-out surface is maintained.
